“'Tantrism' can be viewed as an umbrella term for a specific type of esoteric subset of “Hinduism”—itself a broad category encompassing a multitude of traditions across South Asia, particularly India—and also shares distinct overlaps with Buddhism’s Vajrayana tradition, prevalent in regions such as Nepal. Prior to the 19th Century, this phenomenon received little attention from historians of religion, orientalists, or occultists, partly because it represents a specialized—constructed, if you will—category of spirituality rooted in India and oriented toward esoteric practices.

A leading authority in the study of this field is the Italian thinker Julius Evola (1898–1974). During his late teens and twenties, he acquired extensive knowledge of the world’s major religions and their esoteric dimensions, culminating in a series of original and ambitious works that straddle popular scholarship and instructional manuals for a primarily spiritual elite. The first edition of his book, L'uomo come potenza (1925), was retitled Lo yoga della potenza in its third edition (1949). Inner Traditions’ 1992 English translation is titled The Yoga of Power: Tantra, Shakti, and the Secret Way."
